Step-by-step explanation:
f(x) = 2/(x-3) is a rational function
4 = (3x^2 - 5x +2) / (x + 2) is a rational equation
2x - 7 < x + 1/(x - 2) is a rational inequality
An expression is rational in simplest form if it can be written as N/D where N and D have no common factors.
So 2/3 and (x-2)/x^2 and (3x^2 + 3x)/ (2x + 7) are all rational expressions
